“Ibn Abdul-Rahman, the Imam, the Hafidh, the Shaykh Al-Islam, the scholar of the lands of Egypt, Abu Al-Harith Al-Fahmi MAWLA (client) of Khaled Ibn Thabit Ibn Dha’en and his family used to say: ‘We are PERSIANS from ISFAHAN’ and there is no contradiction in what they said (as Isfahan is one of the ancient Persian cities).”

It can easily be argued that the vast majority of the non-Arab Salaf were of Persian origin, in particular the major scholars of ALL fields (Fiqh, Hadith, Arabic Grammar etc. etc.), especially in the lands of Iraq (that were part of the Persian empire). The service of Persian Sunni scholars to Islam is only understood by those who have studied the early history of Islam and are familiar with the Ansab (lineage) of the scholars and the Sunni history of Persia.
